The vf_drawtext filter uses the GET_UTF8 macro in multiple locations. Each of these use `continue;` as the error handler. However the documentation for the GET_UTF8 macro states "ERROR should not contain a loop control statement which could interact with the internal while loop, and should force an exit from the macro code (e.g. through a goto or a return) in order to prevent undefined results."
This patch adjusts vf_drawtext to use goto error handlers similar to other locations in ffmpeg. Aaron
